Our invention relates to dough mixing machinery. Y l

'In the manufacture of certain types of dough for particular kinds o'fpastry or cake, it has been customary to mix the doughwithin a mixer andafter a certain treatment to dis charge the contents of the mixer into atrough or other receptacle in which ingredients are Y given some furthertreatment lprior to being returned intovk the mixing machine.

The troughs whichwere originally used for receiving the contents ofthemixer for the intermediate treatmentnor for the addition of otheringredients, is ordinarily Vprovided with wheels or casters sothat itvmay be moved tion shown in Figure 1.-

about the floor of thek mixing room as desired.

To the best of ourv knowledge and belief when doughs and floured batchesare han dled with this intermediate treatment the contentsofthe troughshas hadto beput back into ythe mixer for lfurther treatment. This hasnecessitated considerable'hand labor in passing .the material fromthertrough back into the mixer. It has taken considerable time toaccomplish this and often the quality of the batch is harmed during itshandling.

It is the object of our invention to provide an auxiliary trough forattachment to a dough mixer casing which may be mechanically elevated soas to discharge the contents in a mass directly into the mixer'.

Another object `of our invention is the provision of an auxiliary troughwhich may be so atatched to the mixer bowl that it forms a art of thecover thereof, so that when vkthe bowl is tilted to discharge thecontents the the trough.

It is further the vobject of our invention to provide an auxiliarytrough having wheels or casters to move the same about the floor 'of themixing room, which will have a demountable connection with the mixerbowl so it may readily be disconnected after the contents of.

the mixer has been discharged into it.

A further obgect of our invention is the provision of mechanical meansfor rocking the mixer bowl or casing and at the same timeelevating thestorage trough into position to discharge into kthe mixer.

part of the cover may be elevated to' an in- -tion villustrated' inFigure 3. Y y A. j Referring'first to Figures'l and 2, We have indicateda Y supporting' frame 1"-having vunder'lthe 'conduit 8, havingacontoured flange 9 which'. fits f snugly 'surface ofthe cover. l mixedingredients will discharge directly into lines in'fFigure 2 shows thehook shaped *The above objects and' other objects to which referencewlllbe made inthe ensuing disclosure we accomplish by that certaincombination 'and arrangement of parts-fof n which we have illustratedseveral preferred l55 modications. l,

.Referring to the drawings zV 'f f Figure *1f is anend elevation of adough mixer-1n which a detachable trough forming clinedposition overthemixing bowl so that it` will notinterfere with a conduit throughwhich different ingredients to be'mixed are discharged into the mixer.

Figure 2 is a sideelevation of thecombina- Figure 3 is an end elevationofaV mixing bowlhavingl a storage trough associated therewith, which maybe mechanically: h moved to a position directly above the bowl, and inwhich the trough has an opening in its lbottom through ywhichingredients may be discharged from a conduit'into a mixer.

Flgure 4 1s a sideelevation ofthe combinavjournal blocks 2 whichjournala 'shaft of a mixing bowl indicated at 4. vThe agitator 5 of the mixeris rotated by meansV of an 8 `electric motor indicated at 6.

The bowl .cover 7 is preferably 'of con- .toured shape so thatit willswingo'ut from against lthey upper i The 'coverhas a Vflattened area'10, preferably having a channel 11 which engages the top edge 12 of astorage tank ors trough-'13, They trough illustrated has'casters-ltsothat l ittmay bedrawn about thefloor' of the mixing room as desired.

i As means for demountably securing lthe storage troughl to theflattened portio-nof the bowlcoverwe have shownbosses l5 having Ihoodshaped/clamps 16 which engage lugs 17 formed on'theunder edge oftheflange of the trough. The trough indicated in Vv'dotted' lill-G shown inconnected position has t-he hook shaped clamps engaged to the bosses ofthe trough.

Since many bakers have more than one mixer and since they requirediiierent treatments for the dough batches mixed it is within the scopeof our invention to provide a series of troughs, all of similarconstruction, so that each dough mixer will have more than one troughwhich can be used in co-nnection with it.

In the modification shown in Figures 3 and 4 we have shown thesame'general structure and combination of parts as are illustrated inthe combination shown in Figures :1 andQ. We have provided framesupporting members 'la with journal blocks-2a journaling the'shaft 3aofthe agitator 5a which p rotates withinthe mixing bowl 4a. The topcover 7a of the bowl has la' horizontally fiat opening 10a whichreceives the upper flange 12a of the trough 13a., The trough in themodification shown inFiguresB and has a removable plate 18 which coversthe opening 19 in the bottom-of the trough, so that when the clamps 16aare securedfto the bosses 17a `of the bowl andthe lever 20 whichcontrols the bowl,and the-bowl is moved, to the .position indicated inFigures 3 and 4, the cover plate 18 may be opened upandthe ingrethemotor 21which`actuat'es the rocking of `dients to be 'mixed may bedischarged through the trough into the opening.` pf

We have only illustrated two preferred modifications in whichdemountable troughs the mixer through are associated with mixing'bowlsr`and pro-l vided with suitable'connections so that the trou hs can beelevated with-the bowls into suita le positions to discharge-hitok themixers, but various mechanical modifications-will occurto others foraccomplishingthis` same purposewithout departing from the spirit ofour-invention. c
